Take a look at the size of this thing compared to my normal garden hose!!!!!
I had a Parker 5/8" x 75' to begin with. Very good quality hose and fittings. Very pleased with it. I paid like $50 for it last year. It still looks and operates like new.
Then I just ordered the Underhill 3/4" and 1" hose (1" needs adapters) to compare. Both in 75 feet.
The nozzles I use I posted in a video in this thread. I use the yellow for flower beds and the blue one for grass or heavy watering.
So I just compared the same hose except in 3/4" to my 1". Noticeable difference. The 1" really wins if you are using a nozzle that can utilize the extra through-put. It's the one and only thing I own that is better than what @wardconnor has!! LOL

Underhill makes quality products. :thumbup: If you use the hose for different things you should buy quick disconnects. You'll wonder how you lived life without them.

Did you measure the flow rate of both? It's been a while, but wouldn't they be the same if the supply line was smaller than the hose? edit: I guess the pressure behind it would make all the difference.

What size water supply are you connecting to and at what pressure? I am running off a 3/4 inch supply to a full flow 3/4 inch hose bib connected to a 100ft 3/4 inch hose at 75 psi and put out around 12 gpm. I have tried high flow nozzles but don't have the gpm flow to get a good pressure stream. Not sure how Increasing hose diameter without changing the supply size would make a material difference. Maybe if we have an irrigation engineer on the forum they could clarify. I am all for reducing hand watering time.

I have a standard hose spigot that is located right next to the main water line into the house. Last time I had a plumber out, he said I had high water pressure, though I don't remember the number.
We ran my 5/8" hose, the new 3/4" (which I just returned) and the new 1" (which I am keeping). With the fixed Underhill blue fan nozzle, there was a noticeable difference with the distance, size of fan spray, and amount of water being put out.
Wife thought I was nuts but then she watched and even she admitted there was a difference. Length of hose is 75'.
I can't get technical and talk like an engineer. I can only say what we both witnessed in our test.

If your supply to the spigot is the standard 1/2" and there is indeed is a difference, the 1" hose wouldn't be needed (quality aside). You can use the adapter (on a 1/2" hose) for the larger nozzle and get the same result.

I have accidentally cut into my water supply line before while digging. It is much larger than that. It looked to be a 1.5" line.
Look, guys, you can guess and hypotosize all you want. Just come by my house and watch for yourself. I actually tested it out. Believe me, I could have saved $175 if the test showed otherwise. I wouldn't have wasted the money if there were no difference.
@DFW_Zoysia a larger diameter hose is going to have less pressure loss no matter what size piping/spigot it is connected to. Pressure losses are cumulative - irrigationtutorials.com explains it like this:
Like all other mechanical systems an irrigation system consumes energy when it operates. The irrigation system uses energy in the form of water pressure which, as we noted earlier, we will be measuring in PSI (pounds per square inch). Each component in the irrigation system that the water passes through consumes a little bit of that water pressure. It's similar to how a car uses up fuel for each mile it goes. If we run out of water pressure before the water makes it through the system, then the irrigation system will not work. Therefore, we need to calculate how much pressure will be lost as the water passes through each component of the irrigation system.
So basically every component between the city's water main and your nozzle is going to cause some pressure loss - every valve, fitting, foot of pipe/hose, etc. But let's ignore everything upstream of your spigot because you can't easily change that. Just understand that the water pressure at the spigot is the water pressure supplied by the city, less the sum of all the pressure losses associated with every upstream component in your piping system.
So let's say the water pressure at your spigot is 50psi. That is going to be the same hose inlet pressure no matter what size hose you choose. However, the pressure at the end of the hose is going to be that 50psi, less the pressure loss associated with the hose - and at any given flow rate, a larger diameter hose is going cause less pressure loss:
I know you are using a 75ft hose, but to align with the chart above, let's say it is 100ft long and your flow rate is 5gpm. A 5/8" hose would have a ~9psi drop, a 3/4" hose would have a ~3.75psi pressure drop, and a 1" hose would have a ~0.9psi pressure drop.
To better understand the relationship between flow and pressure, I recommend reading this article.

Thanks Ware. So this confirms what I noticed in my experiment - that the 1" hose with the fixed blue Underhill nozzle compared to the 5/8" hose with the same nozzle had a significant higher output of water. Both hoses were 75' long, and both were stretched out straight from the spigot to minimize variables.
